Role of Acoustic Radar in Earthquake Precursor Detection

Abstract

 In the field of earthquake precursors, most of the researchers are now realizing that the feeble amount of energy /mass /momentum etc. released prior to main rapture by a major earthquake, should be good enough to cause large amount of changes in the atmospheric parameters which can be easily detected. The above requirement of monitoring can only be fulfilled by techniques like acoustic radar /Lidar that monitor atmosphere in pictorial form on 24-hour basis or use satellite-based monitoring. The data must be processed within minimum possible time and the conclusions must be drawn in order to issue the most wanted warning of an impending earthquake. It is important to note that in India, a major earthquake with magnitude of >8.0 is overdue and we need to address this issue of precursor detection on priority.

    We at the Silver Line Prestige School are working on acoustic radar technology which maps the dynamics of the lowest 1 km of the atmosphere as it presents data in the photographic form. The problems associated in utilizing this technique are presented in this  paper
